Name of the Vulnerable Software and Affected Versions pam usb versions prior to 0.8.7

Description An issue exists in the hardware authentication system for Linux where shell injection can occur. A crafted UUID in the configuration can lead to root remote code execution when the pamusb-conf --reset-pads command is executed. This payload can be injected during the --add-device process via a USB device with a crafted filesystem UUID. Additionally, the userName variable from the XML configuration is passed to the os.system() function in pamusb-agent, which invokes a shell.

Recommendations Update to version 0.8.7.
